HE Dyes
Introduction to HE Dyes
HE Dyes, or high exhaust dyes, are based on “Bis-Monochloro Triazine” Reactive system. This type of dye is ideal for dyeing cotton and other cellulosic materials. These dyes possess significantly higher exhaustion and fixation efficiency which results in appreciable cost reduction compared to conventional reactive dyes. The high fixation and good build-up are particularly important when dyeing polyester/cellulosic blends, where the liquor to goods ratio is quite high.
One of the advantages of Reactive HE Dyes is that the drained and washed liquors after dyeing contain much less quantity of unfixed dyes, making them of interest when pollution control is a major concern. This also facilitates quicker wash-off and efficient soaping. The improved stability of HE Dyes provides improved batch-to-batch consistency.
Exhaustion of HE reactive dyes can be controlled by salt addition and temperature to give level dyeing before alkali addition. Overall, HE Dyes are suitable for dyeing cotton and other cellulosic materials due to their superior exhaustion and fixation properties.

Properties of HE Dyes
- Higher exhaustion efficiency: HE Dyes have a significantly higher exhaustion efficiency compared to conventional reactive dyes. This means that a smaller amount of dye is required to achieve the desired level of coloration, resulting in cost savings.
- Good fixation: HE Dyes have excellent fixation properties, which means that they bind well to the fibers and are less likely to wash out or bleed during subsequent washings.
- Improved stability: HE Dyes have improved stability, which ensures consistency and batch-to-batch reproducibility of the dyeing process.
- Low unfixed dye content: The drained and wash liquors after dyeing contain much less quantity of unfixed HE dyes compared to conventional reactive dyes. This is important for pollution control and efficient washing and soaping.
- Controlled exhaustion: The exhaustion of HE Dyes can be easily controlled by adjusting the salt addition and temperature before alkali addition, resulting in level dyeing.
Advantages of HE Dyes
HE Dyes, or Highly Exhausted Dyes, have several advantages that make them a popular choice for dyeing cotton and other cellulosic materials. These advantages include:
- Cost savings: HE Dyes have a significantly higher exhaustion efficiency, which means that a smaller amount of dye is required to achieve the desired level of coloration, resulting in cost savings.
- Better fixation: HE Dyes have excellent fixation properties, which means that they bind well to the fibers and are less likely to wash out or bleed during subsequent washings. This results in a more vibrant and long-lasting colour.
- Improved environmental sustainability: The reduced quantity of unfixed dye in the drained and washed liquors after dyeing means that HE Dyes are more environmentally sustainable than conventional reactive dyes. They also require less water and energy during the dyeing process.
- Controlled exhaustion: The exhaustion of HE Dyes can be easily controlled by adjusting the salt addition and temperature before alkali addition, resulting in level dyeing and better reproducibility.
- Versatility: HE Dyes are suitable for dyeing a wide range of cotton and cellulosic materials, including blends with polyester, making them a versatile choice for various textile applications.
Overall, the advantages of HE Dyes include cost savings, improved fixation, environmental sustainability, controlled exhaustion, and versatility. These benefits have made HE Dyes a popular choice for dyeing cotton and other cellulosic materials.
